How do I prevent orders from being displayed repeatedly on the checkout screen when selecting multiple times
0
For my store, I basically have a quantity box with an add item option. When I select the quantity and click on the add item, the order gets added to my list of orders and it is displayed on checkout. However, Suppose I Select Order A for the first time and set quantity as 5. The second time, I selected Order A again and set quantity as 3, I want it to add to the previous order and display quantity as 8. However, in case of my code, it displays it as separate orders. How do I solve this issue?
views.py
def addItem(request):
selected_supply = Supply.objects.get(pk=request.POST['supplyID'])
qty = request.POST['qty']
try:
current_order = Order.objects.filter(owner=1).get(status="pre-place")
except Order.DoesNotExist:
current_order = Order.objects.create(owner=Manager.objects.get(pk=1), status="pre-place")
order_detail = OrderDetail.objects.create(orderID=current_order, supplyID=selected_supply, quantity=qty)
return HttpResponseRedirect(reverse('Store:browse'))
models.py
class OrderDetail(models.Model): #change to orderitem
orderID = models.ForeignKey(Order, on_delete=models.CASCADE)
supplyID = models.ForeignKey(Supply, on_delete=models.CASCADE)
quantity = models.IntegerField()
def __str__(self):
return f'{self.orderID.pk}: {self.supplyID.name} {self.quantity}'
class Order(models.Model):
owner = models.ForeignKey(ClinicManager, on_delete=models.CASCADE)
priority = models.CharField(max_length=200, blank=True)
weight = models.DecimalField(max_digits=4, decimal_places=2, default=0.00)
status = models.CharField(max_length=200)
placeTime = models.DateTimeField(default=datetime.now())
dispatchTime = models.DateTimeField(default=datetime.now())
deliveredTime = models.DateTimeField(default=datetime.now())
def __str__(self):
return f'{self.pk}'
def __lt__(self, other):
if (self.priority == other.priority):
return self.placeTime < other.placeTime
elif (self.priority == "High"):
return True
elif (other.priority == "Low"):
return True
else:
return False

What'sOrderDetailandSupplyin this? You only talk aboutOrderin your description. Please be more specific about what's happening, and what result you're expecting in terms of the objects you use in your view. Rephrase your own question rather than adding details in the comments.

Sorry. I forgot to add the models/ Order detail contains the order ID supply ID and quantity. My order consists of the owner, weight, status, priority, dispatch time etc

"I select Order A" doesn't make sense looking at your view, since theOrderobject isn't determined by any selection (you don't userequest.POSTparameter to select anOrder).

I'm not sure what you are finding hard here. You already know how to get an existing item and update it, as you do it with Order. Why can't you do the same thing with OrderDetail: find any existing OrderDetail for that order with that supplyId and update its quantity, or if it doesn't exist create a new one.
